RESUMEN

BACKGROUND: A history of child abuse is common and has a significant impact in the clinical course of patients diagnosed with bipolar disorders (BD). AIMS: To assess the frequency of child abuse experiences in patients BD type I and to evaluate its association with clinical course and cognitive functioning variables. MATERIAL AND METHODS: 117 patients with BD aged 45 ± 14 years (66% women) answered the Childhood Trauma Questionnaire (CTQ). The clinical course (illness onset, history of suicide attempts and number of hospitalizations) was obtained from medical records. Cognitive functioning was evaluated through social and non-social cognition tasks. RESULTS: 64% of participants reported some type of child abuse. This variable was associated with an early onset of the disease (Odds ratio (OR) = 3.3; p < 0.02), increased risk of suicide attempts (OR = 2.4; p < 0.04) and specific disturbances in social cognitive tasks. CONCLUSIONS: Our study supports evidence of a common history of child abuse in patients with BD. Although child abuse predicts a worse clinical course, major clinical practice guidelines, as well as research designs, do not highlight this evidence.

RESUMEN

BACKGROUND: Quality of life and psychological well-being are readily hampered by depression. The changes that students face during college life impact their psychological health and well-being, including the emergence of mental health problems like depression Aim: To determine the relationship between depressive symptoms, sociodemographic parameters and psychological well-being in undergraduate university students. MATERIAL AND METHODS: Five hundred eighty university students of both sexes, from the Metropolitan and IX Regions of Chile answered the Beck Depression Inventory (BDI-IA) and the Ryff's psychological well-being scale. RESULTS: Twenty eight percent of respondents had clinically significant depressive symptoms, and these were more frequent in women. There was an inverse and statistically significant relationship between psychological well-being and depressive symptoms. This fact was especially marked in dimensions of autonomy, positive relationships with others and purpose in life. CONCLUSIONS: There is a high frequency of depressive symptoms among these students. We discuss whether psychological well-being and depressive symptomatology represent two extremes within a continuum or they are two independent dimensions that can account for differential causal mechanisms linked to mental health and illness.

RESUMEN

BACKGROUND: Diverse and sustained efforts have been developed to improve the management of depression by general practitioners (GPs), but they have not improved treatment coverage and quality of services. AIM: To explore the level of knowledge and clinical skills to diagnose and treat depression by GPs in Primary Health Care (PHC) in the Metropolitan Area of Santiago de Chile (RM). MATERIAL AND METHODS: Theoretical knowledge (TK), diagnostic skills (DS) and treatment skills (TS) were evaluated in 56 GPs of the RM with a battery of specially designed instruments. RESULTS: In TK there were significant differences between GPs aged 31 years or less and their older counterparts and between Chilean and foreign doctors. Five percent of observed differences in TK were explained by age and nationality, respectively. Chilean GPs achieved higher scores in recognition of symptoms (RS), one of the dimensions of DS. No significant differences by age or nationality were observed for DS and TS. CONCLUSIONS: Achievement of GPs on tests measuring TK, DS, and TS was generally below 50%. This deficiency should be improved.

RESUMEN

BACKGROUND: There are suggestions that, despite training efforts for Primary Health Care physicians, difficulties in making accurate diagnoses and timely treatments persist. AIM: To evaluate the impact of a new training model in Depressive disorders integrated with Mindful Practice, on the diagnostic and therapeutic skills of primary care general physicians. MATERIAL AND METHODS: A voluntary sample of 56 general physicians was studied. The design of this study was experimental and randomized, with two groups attending theoretical sessions followed by differing workshops that were carried out in a parallel fashion. The Quantitative phase of this study considered measuring the impact of training in physician's skills. The Qualitative phase included nine semi-structured interviews and Qualitative Content Analysis. This paper reports the results of the interviews. RESULTS: As a consequence of training sessions, physicians learned that above the mental health problems, other issues such as self-efficacy and self-confidence are important for the management of depressive patients. CONCLUSIONS: This qualitative study shows that physicians are obtaining significant benefits from their training sessions.

RESUMEN

Depression has a high impact on mental health. However its diagnosis is a challenge even for specialists. This problem derives from a failure in an adequate description and differentiation of the disease. This inadequate conceptualization generates these difficulties. Our thesis is that depression should be understood as a complex phenomenon that can be analyzed from multiple perspectives, from genes to behavior, including personality and interaction with the sociocultural environment. The aim of this paper is to review the psychopathological construct of depression from a multidimensional point of view, considering clinical, sociocultural, characterological and pathogenic variables. Finally we provide a proposal for an adequate diagnostic approach.

RESUMEN

Background: Most studies on cognitive impairment in bipolar disorder have neglected the role of early stress, despite the high frequency of childhood maltreatment in this clinical group. The aim of this study was to establish a connection between a history of emotional, physical, and sexual abuse in childhood and social cognition (SC) in patients with bipolar disorder type I (BD-I) in euthymia, and to test a possible moderating effect of the single nucleotide polymorphism rs53576 in the oxytocin receptor gene (OXTR). Methods: One hundred and one participants were included in this study. History of child abuse was evaluated using the Childhood Trauma Questionnaire-Short Form. Cognitive functioning was appraised using The Awareness of Social Inference Test (social cognition). The interaction effect between the independent variables OXTR rs53576 (AA/AG and GG) and the absence or presence of any one type of child maltreatment or a combination of types was analyzed using a generalized linear model regression. Results: BD-I patients who had been victims of physical and emotional abuse in childhood and were carriers of the GG genotype at OXTR rs53576 displayed greater SC alterations, specifically in emotion recognition. Discussion: This gene-environment interaction finding suggests a differential susceptibility model of a genetic variants that can be plausibly associated with SC functioning and might help to identify at-risk clinical subgroups within a diagnostic category. Future research aimed at testing the interlevel impact of early stress constitutes an ethical-clinical duty given the high rates of childhood maltreatment reported in BD-I patients.

RESUMEN

Genetic and early environmental factors are interwoven in the etiology of Borderline Personality Disorder (BPD). Epigenetic mechanisms offer the molecular machinery to adapt to environmental conditions. There are gaps in the knowledge about how epigenetic mechanisms are involved in the effects of early affective environment, development of BPD, and psychotherapy response. We reviewed the available evidence of the effects of psychotherapy on changes in DNA methylation and conducted a pilot study in a sample of 11 female adolescents diagnosed with BPD, exploring for changes in peripheral DNA methylation of FKBP5 gene, which encodes for a stress response protein, in relation to psychotherapy, on symptomatology and underlying psychological processes. For this purpose, measures of early trauma, borderline and depressive symptoms, psychotherapy outcome, mentalization, and emotional regulation were studied. A reduction in the average FKBP5 methylation levels was observed over time. Additionally, the decrease in FKBP5 methylation observed occurred only in those individuals who had early trauma and responded to psychotherapy. The results suggest an effect of psychotherapy on epigenetic mechanisms associated with the stress response. The finding that epigenetic changes were only observed in patients with early trauma suggests a specific molecular mechanism of recovery. The results should be taken with caution given the small sample size. Also, further research is needed to adjust for confounding factors and include endocrinological markers and therapeutic process variables.

RESUMEN

(1) Background: There is consistent evidence of the impact of early adverse experiences on mental health in adulthood, especially as a risk factor for depression. However, their influence on positive aspects of mental health such as well-being has been less extensively studied. Therefore, this study aims to investigate the effect of traumatic childhood experiences on the relationship between depression and psychological well-being in a sample of university students. (2) Methods: The Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Beck Depression Inventory (BDI-IA), and Ryff's psychological well-being scale were administered to 700 Chilean university students. Several regression models were used to analyze the interaction between variables, with multivariate SEM being applied to hierarchize the relationships found. (3) Results: Emotional Neglect and Abuse stand out as the types of maltreatment with the greatest impact on mental health, associated first with a decrease in the self-acceptance dimension of psychological well-being and then with depressive symptomatology in adulthood. (4) Conclusions: Results provide evidence that early trauma has an important impact on mental health, increasing the risk of depression, however, its impact is greater on positive aspects of health, such as self-acceptance, a fundamental element in the construction of psychological well-being.

RESUMEN

BACKGROUND: A change in the social structure of medicine and its impact on clients has occurred in the last decades. AIM: To perform a survey about subjective wellbeing among physicians. MATERIAL AND METHODS: A physician’ professional satisfaction survey consisting in 90 questions, was applied to 580 physicians (70% males), working in Metropolitan Santiago. RESULTS: Physicians perceive changes in all the examined professional domains and approximately 50% of the changes are evaluated as negative. Change perception is a general phenomena among physicians, since there were no differences in relation to gender and only in few aspects with respect to age and medical specialty. There was a predominant positive attitude, based on the profession, to face changes. CONCLUSIONS: The positive evaluation of changes and the frequent use of managing strategies are associated with a higher satisfaction among physicians.

RESUMEN

After more than a century of existence, theoretical development, research, and clinical practice within the psychoanalytic movement have consistently demonstrated that psychoanalysis is not a unitary and autonomous discipline. This has been evidenced by the various ways in which psychoanalytic thought and practice have been informed by and have established a dialogue-more or less fruitful-with related disciplines (neurosciences, developmental psychology, psychotherapy research, attachment theory and research, feminism, philosophy). This dialogue has contributed to a better understanding of the functioning of the human psyche, and therefore of the analytic process, informing clinical interventions. In turn, it has enriched research on psychoanalytic practice and process, underlining the fact that research in psychoanalysis is fundamentally about clinical practice. Since its origins, psychoanalysis has made explicit the work on the patient-analyst relationship as the terrain in which the analytic process unfolds. For its part, research in psychotherapy has demonstrated the relevance of the therapeutic relationship for the good development and outcome of any psychotherapeutic process. This supports the argument that research in clinical psychoanalysis should be research on the impact of the analyst interventions on the analyst-patient relationship. In this context, a central element of what happens in the analytic relationship refers to affect communication and therefore, affect regulation, which is manifested in the transferential and counter-transferential processes, as well as in the therapeutic bond. On the other hand, affective regulation is found at the crossroads of etiopathogenesis, complex personality models and psychopathology, allowing the understanding of human functioning and the staging of these configurations in the patient-analyst relationship. In this way, research on affective regulation in the analytic process is proposed as a path that exemplifies interdisciplinary research and scientific pluralism from which psychoanalysis enriches and progresses as a discipline. The case of a line of research on affective regulation in psychoanalytic psychotherapy is illustrated. The need to resort to other disciplines, as well as the translational value of our research and its clinical usefulness, is discussed.

RESUMEN

In 100 years of clinical research and 40 years of empirical research, the concept of psychoanalytic process continues to elude a consensual definition, probably because the problem and methodology must be approached in a different way. This article outlines the empirical implications of the epistemological model exposed in a previous article, by proposing a scientific, innovative, and clinically sensitive research programme for the study of psychoanalytic process. This proposal is an attempt at developing psychotherapy research that is founded on psychoanalytic hypotheses derived from a two-person psychology. The research programme focuses on the interactional nature of the analytical work, and on the relationship between the implicit (unconscious) and the explicit (conscious) levels of the analytic endeavour. The authors propose that this research programme be articulated around three methodological approaches: (1) the use of systematic case studies; (2) the adoption of the events paradigm for accessing the salient phenomena of the psychoanalytic process; and (3) a micro-analytic approach to the specific phenomena occurring within relevant sequences of interaction. These ideas are illustrated with a description of the micro-analysis of a clinical case. This article is intended to contribute to a constructive dialogue between psychoanalytic practice and psychotherapy research.

RESUMEN

The central objective of this presentation is to reflect on the obstacles involved in the task proposed by the Chicago Congress, which is to explore convergences and divergences in psychoanalytic practice. The author discusses two major obstacles. First, the epistemological and methodological problems in relation to the construction of theory in psychoanalysis and especially the inaccessibility, in any reliable way, of what psychoanalysts really do in the intimacy of their practice. He proposes to separate, at least in part, theory from practice in psychoanalysis, in an attempt to grasp psychoanalysts' practice in its own merits. He then outlines a phenomenology of the practice of psychoanalysis, which reveals that, in their work with patients, analysts are guided more by practical reasons than theoretical reasons; that is, their interventions are predictions rather than explanations. Since these practical reasons need to be validated constantly in the analytic relationship based on their effects, he discusses the subject of validation in the clinical context of the core theory of therapeutic change in psychoanalysis, that is, the conditions required for clinical practice to satisfy the thesis of an inseparable union between gaining knowledge and cure. He ends by challenging the core of the psychoanalytic theory of change, arguing that it neither does justice to the practice of psychoanalysts nor to contemporary knowledge of processes and mechanisms of therapeutic change. Finally, he proposes that we detach practice from theory, in order to study the former in its own merits, utilising a plurality of methods ranging from systematic investigation to the recent methodology of the Working Party.

RESUMEN

This article is devoted to the topic of the conditions for a constructive interdisciplinary dialogue between psychoanalytic theory and practice and research in mind disciplines neighbouring psychoanalysis applied to the concept of psychoanalytic process. The first section reviews the contemporary controversy about psychoanalysis and research and the contributions that different disciplines-such as empirical research in progress in psychotherapy and psychoanalysis, in attachment and the early mother-infant relationship, and neurosciences-propose for the construction of theory in psychoanalysis. The gaps in the scientific investigation of central aspects of the psychoanalytic conception are highlighted, such as the dyadic nature of the construction of the experience in therapy and the relationship between the implicit and explicit levels of the analytic relationship. The article concludes by laying the foundations for a novel research programme for psychoanalysis that addresses the outstanding gaps.

RESUMEN

El trauma es la principal causa de muerte de la población en edad productiva. El abordaje del trauma torácico cerrado todavía es un desafío para el médico de urgencias. Aunque no es una entidad frecuente, se asocia con una alta mortalidad y resultados adversos. El diagnóstico del trauma cerrado de aorta torácica (LCAT) requiere un alto índice de sospecha, dado que los signos y síntomas no son específicos de esta enfermedad (dolor torácico, dolor interescapular, disnea, disfagia, estridor, disfonía). Es importante resaltar que la ausencia de inestabilidad hemodinámica no debe descartar una lesión aórtica. Para su diagnóstico imagenológico se debe tener en cuenta que los rayos X de tórax no tienen el rendimiento adecuado, el patrón de referencia es la angiotomografía y el ecocardiograma transesofágico (ETE) constituye una opción diagnóstica. El manejo incluye líquidos endovenosos y antihipertensivos como medida transitoria, manejo quirúrgico definitivo y, en algunos casos, manejo expectante o diferido. Los pacientes inestables o con signos de ruptura inminente deben ser llevados de manera inmediata a cirugía. El manejo quirúrgico temprano ha impactado en la mortalidad. A pesar de los avances en las técnicas quirúrgicas, la técnica quirúrgica abierta documenta mayor tasa de mortalidad que el manejo endovascular, el cual tiene numerosas ventajas al ser poco invasivo. Esta es una revisión narrativa que destaca algunos aspectos clave sobre los mecanismos de lesión, diagnóstico y manejo inicial del trauma cerrado aorta torácica. Por último, se propone un algoritmo de abordaje de trauma de aorta.


Trauma is the leading cause of death in the productive-age population. Addressing blunt chest trauma is still a challenge for the emergency physician. Although it is not a common entity, it is associated with high mortality and adverse outcomes. The diagnosis of blunt thoracic aortic trauma (LCAT) requires a high index of suspicion, given that the signs and symptoms are not specific to this disease (chest pain, interscapular pain, dyspnea, dysphagia, stridor, dysphonia). It is important to highlight that the absence of hemodynamic instability should not rule out aortic injury. For its imaging diagnosis, it must be taken into account that chest X-rays do not have adequate performance; the reference standard is angiotomography and transesophageal echocardiography (TEE) is a diagnostic option. Management includes intravenous fluids and antihypertensives as a temporary measure, definitive surgical management and, in some cases, expectant or deferred management. Unstable patients or patients with signs of imminent ruptura should be taken immediately to surgery. Early surgical management has impacted mortality. Despite advances in surgical techniques, the open surgical technique documents a higher mortality rate than endovascular management, which has numerous advantages as it is minimally invasive. This is a narrative review that highlights some key aspects about the mechanisms of injury, diagnosis and initial management of blunt thoracic aortic trauma. Finally, an algorithm for addressing aortic trauma is proposed.

RESUMEN

The author begins by characterizing the present situation of psychoanalysis as one of increasing theoretical and practical diversity. The aim of this paper is to consider in depth the impact of theoretical plurality on clinical practice. After noting that the analyst has much more than evenly suspended attention in his(2)mind as he works with his patient in a session, the author reviews both older and more recent contributions on what the analyst has in his mind when working with a patient. He suggests that the subject has been addressed mainly from a single-person perspective. In this connection, and on the basis of clinical material, he attempts to show how, against the background of the 'implicit use of explicit theories', an ongoing process of decision-making that is co-determined by the patient's action and reaction takes place in the analyst's mind. In his analysis of a session, the author introduces the concepts of theoretical reason and practical reason, and contends that, whatever theories the analyst may have implicitly or explicitly in his mind, they ultimately yield to practical reasons. Pursuing the same line of thought, he describes validation in the clinical context as a single, wide-ranging, continuous process of social and linguistic co-construction of the intersubjective reality between patient and analyst. This process includes mutual aspects of observation and of communicative and pragmatic validation. In conclusion, he suggests that the figure of the craftsman is an appropriate description of the analyst in this conception of his work.

RESUMEN

The heterogeneity of exosomal populations has hindered our understanding of their biogenesis, molecular composition, biodistribution and functions. By employing asymmetric flow field-flow fractionation (AF4), we identified two exosome subpopulations (large exosome vesicles, Exo-L, 90-120 nm; small exosome vesicles, Exo-S, 60-80 nm) and discovered an abundant population of non-membranous nanoparticles termed 'exomeres' (~35 nm). Exomere proteomic profiling revealed an enrichment in metabolic enzymes and hypoxia, microtubule and coagulation proteins as well as specific pathways, such as glycolysis and mTOR signalling. Exo-S and Exo-L contained proteins involved in endosomal function and secretion pathways, and mitotic spindle and IL-2/STAT5 signalling pathways, respectively. Exo-S, Exo-L and exomeres each had unique N-glycosylation, protein, lipid, DNA and RNA profiles and biophysical properties. These three nanoparticle subsets demonstrated diverse organ biodistribution patterns, suggesting distinct biological functions. This study demonstrates that AF4 can serve as an improved analytical tool for isolating extracellular vesicles and addressing the complexities of heterogeneous nanoparticle subpopulations.

RESUMEN

After briefly reviewing the unfavourable reception accorded empirical research by parts of the psychoanalytic community, as well as some of the benefits to clinical practice of analysts being involved in research activities, the author examines whether the findings of process and outcome research in psychotherapy and psychoanalysis can help identify the most appropriate forms of intervention for producing therapeutic change, given the specific condition of the patient and the relationship that the individual establishes with the analyst. He argues that research findings can influence clinical practice on various levels and in different areas, and goes on to examine a number of related issues: the specificity of therapeutic interventions versus the relevance of common curative factors; the dyadic conception of technique and ways of understanding the therapeutic action of the treatment alliance; and the strategic or heuristic conception in psychoanalytic therapy. Finally, the author presents clinical material with the aim of illustrating how the knowledge acquired through research can be applied to psychoanalytic treatment.

RESUMEN

Research on the potential role of gene-environment interactions (GxE) in explaining vulnerability to psychopathology in humans has witnessed a shift from a diathesis-stress perspective to differential susceptibility approaches. This paper critically reviews methodological issues and trends in this body of research. Databases were screened for studies of GxE in the prediction of personality traits, behavior, and mental health disorders in humans published between January 2002 and January 2015. In total, 315 papers were included. Results showed that 34 candidate genes have been included in GxE studies. Independent of the type of environment studied (early or recent life events, positive or negative environments), about 67-83% of studies have reported significant GxE interactions, which is consistent with a social susceptibility model. The percentage of positive results does not seem to differ depending on the gene studied, although publication bias might be involved. However, the number of positive findings differs depending on the population studied (i.e., young adults vs. older adults). Methodological considerations limit the ability to draw strong conclusions, particularly as almost 90% (n = 283/315) of published papers are based on samples from North America and Europe, and about 70% of published studies (219/315) are based on samples that were also used in other reports. At the same time, there are clear indications of methodological improvements over time, as is shown by a significant increase in longitudinal and experimental studies as well as in improved minimum genotyping. Recommendations for future research, such as minimum quality assessment of genes and environmental factors, specifying theoretical models guiding the study, and taking into account of cultural, ethnic, and lifetime perspectives, are formulated.

RESUMEN

After a restatement of the isolationism of psychoanalysis from allied disciplines, and an examination of some of the reasons for the diversity of schools of thought and the fragmentation of psychoanalytic knowledge, the author suggests the need to adopt principles of correspondence or external coherence along with those of hermeneutic coherence to validate psychoanalytic hypotheses. Recent developments in neurocognitive science have come to the aid of psychoanalysis in this period of crisis, resulting in the proposition of integrating both areas to form a new paradigm for the construction of the theory of the mind. This emerging paradigm tries to integrate clinical knowledge with neurocognitive science, findings from studies on the process and outcome of psychotherapy, research into the early mother-infant relationship, and developmental psychopathology. The author examines theoretical- technical models based on the concept of drives and of relationships in the light of interdisciplinary findings. He concludes that the relational model has a broad empirical base, except when the concept of drives is discredited. Interdisciplinary findings have led to the positing of the replacement of the Freudian model of drives with a model of motivational systems centred on affective processes. He draws certain conclusions which have a bearing on the technique of psychoanalytic treatment. These arise from the adoption of the new integrated paradigm.

RESUMEN

The authors provide a perspective on how psychoanalytic process research can be implemented. This is based on a process research model described elsewhere and summarizes the kinds of studies that can be situated on the four levels of the model. The authors summarize multiple empirical studies that were performed in a completely tape-recorded psychoanalytic therapy and have been published. These studies demonstrate the many modalities empirical process research has available to objectively study psychoanalytic process phenomena and their implication for outcome.
